[OpenLayers-Users] Zoom to a Layer's Extent

[Bill Thoen]

Never mind... I just figured out that getDataExtent() applies to 
markers, not features like polygons and linestrings.  Does anybody know 
if there is a function for WFS layers that returns the bounding box of 
that layer regardless of what type of map objects it contains?
